ments in Measuring and Indicating Devices,

'ofwhich the following is a full, clear, and

- exact description.

This invention relates to measuring and indicating devices, and more especially to thatclass thereof which are generally used for determining the lengths of different materialswhich are to be wound on spools or similar elements; and it has for one of its objects the provision of a mechanism whereby the length of the material to be measured andwound upon a spool can be accurately determined and cut off as soon as such predetermined length has been reached.

[My invention has, furthermore, for its object'the organization of a mechanism of this characterwhich mayalso be utilized to de- Qtermine the amount of material which can a be wound upon a spool of any predetermined size. v

j CMyinvention has, furthermore, for itsobj ect the provision of means whereby the registering elements may be set to correspond with different requirements, these elements being frictionally driven so that the operator maybeenabled to set the mechanism to any desired figures.

I My invention has, furthermorafor itsv object the combination with the rotatable drum which is operated by the material as it I ispulled along of a cutting device which is automatically thrown into engagement with the material y the winding mechanism,

andsevers the latter at the completion of a certain number of rotations of the drum.

A iurtherobject of the invention resides in the combination, with the operating drum of thedevice, of a brake mechanism whereby J: the movement of salddrum Wlll be instantly e, checked or arrested upon the breakage of the material to be measured.

. li/iyinvention has, furthermore, for its object theprovision of a mechanism of this F character, the operating parts of which, are

I in'closed within a casing which is adapted to -holda' quantity of lubricating oil and which at the same time is so constructed as to prevent leakage or the spreading of the o l beyond the confines of the casing.

My invention has, also, for its object the construction of the casing (which contains the several elements of the device) in such a manner as to adapt the same for use either righthanded or lefthanded, as occasion may demand and without requiring any changes in the interior mechanism while only the substitution of a single outer bracket for another will be required to change the device from a right handed to a left handed one, or

vice versa.

Other objects of the invention vflll hereinafter appear and the attainment thereof will be pointed out in the claims.

My invention has been fully illustrated in the accompanying drawings in which similar characters denote similar parts, and in which,

Figure 1 is a top view of my improved mechanism, showing the cover and casing in section on line 1 of Fig. 5. Fig. 2 is a side view thereof, the material to be measured being represented as a thread, the tension of which retains the brake in its non-operative position; Fig. 3 is a fractional view corresponding to Fig. 2, and represents the brake in operation, and in the position which it will occupy when the thread is broken; Fig. i is a front view of my improved measuring device; Fig. 5 shows a longitudinal vertical section on line 55, Fig. 1; Fig. 6 is a cross section on line 6*6, of Fig. 1; Fig. 7 is a similar view taken on line 77, of Fig. 1; Fig. 8 illustrates, per se, one of the elements which are to be set by hand according to the amount of material to be measured; Fig. 9 is a front view, illustrating one of the hand-set devices disconnected from the mechanism which normally drives it, and Fig. 10 is a top view of the device corresponding to Fig. 9. Fig. 11 is a sectional detail view of the cutter cam, on line 11 of Fig. 5.

Yihile my improved mechanism may be used for the purpose of measuring and indi cating the lengths of different materials, it is especially designed for use in connection with thread to be wound upon spools of certain capacities, the thread being in the present instance looped around a drum, the circumference of which is equal to a certain fraction or part of a yard, the present drum being of such size that each rotation thereof corresponds to the travel of one-fourth of a I yard of thread, so that in other words, four rotations of the drum will reel one yard of thread.

Briefly stated, the measuring drum actuates in the present case a pointer which is mounted for revolution and coeperates with a stationary disk which is preferably graduated into one hundred divisions, each division representing one yard, so that consequently for each four hundred rotations of the drum, the pointer will make one complete revolution relative to the disk. The drum also rotates a secondary indicating disk or dial which in the present instance is divided into fourteen principal sections, each having ten notches, the disk being constantly driven by the rotation of the drum, but in such a manner that for each complete revolution of the pointer, the index disk will be advanced only one notch, so that consequently the device illustrated in the accompanying drawings is capable of registering fourteen thousand yards.

Referring to the drawings, 20 denotes a drum the circumference of which equals in the present instance one-fourth of a yard, and which has the flanges 21, 22, between which the thread to be measured is retained, the latter being wound around the drum once so as to get a bite for rotating the same. The drum is mounted upon the shaft 23 journaled in bearings 24 Fig. 6 of a casing 25, in which the several elements of the mechanism are mounted. Rotary movement is imparted from the shaft 23 to a worm spindle 26 Figs. 5 and 6 through the intervention of a worm 27 carried on the shaft 23, and a worm gear 28 rigidly secured upon the spindle 26.

The worm spindle 26 is provided with a worm 29 Fig. 5 in engagement with a worm gear 30 which is carried by transverse spindle 31 having a worm 32 Fig. 7 in engagement with a worm gear 83 Figs. 5 and 6 which is formed in the shape of an annular disk, both sides of which are frictionally engaged in a manner to be hereinafter described, and for actuating the indexing devices above referred to, the mechanism being of such proportion that it will require 56,000 rotations of the thread drum (each representing one-quarter of a yard) to turn the secondary index disk for 360 degrees or one full rotation. The worm 27 on the shaft 23 is also in engagement with a gear 35 Fig. 5 mounted upon a vertically-disposed spindle 36 which is journaled in bearings 37, 38, and carries a worm 39 in engagement with a worm gear 40 consisting substantially of a ring adapted frictionally to drive a pointer 41, the organization in the present instance being such that 400 rotations of the thread drum will be required to revolve the pointer 41 once around and past a series of division marks on a stationary dial 42 carried by the casing. This dial 42 is secured to the front end of a sleeve 43 rigidly held in lug 44 on the casing, and by a nut 45 in screw-engagement with the front end of sleeve (see Fig. 5).

1 The pointer 41 is carried at the front end of a s indle 46 journaled in the sleeve 43 and a so in a bearing depending from the bearing 37 above mentioned, and said spindle 46 carries a fixed collar 47 provided at its rear end with flange 48 which is adapted frictionally to engage one face of the worm gear 40 above described. The other side of this worm gear 40 is engaged by a friction collar 49 Fig. 5 which is adapted for longitudinal movement on the collar 47 and is forced toward the flange 48 by a spring 50, both the flange 48 and friction collar 49 being connected for simultaneous rotation with each other by a pin 51.

From the foregoing it will be understood that the spindle 46 with the collar 47 can be turned by hand relatively to the annular worm gear 40, while on the other hand the spindle 46 with the pointer 41 is frictionally driven by the rotation of the thread drum 20 to indicate the number of yards of thread which pass over said drum, and, as indicated by the divisions on the stationary dial 42.

In order to facilitate the count of a greater number of yards of thread, and also for the purpose of limiting the amount of thread (which in the present instance may be up to 14,000 yards), the secondary measuring ring or dial is operated from the drum at a very much reduced ratio, the worm gear 33 Fig. 5 forming a part of this mechanism and d riving in a frictional manner a sleeve 55 mounted for rotation on the stationary sleeve 43 and having a flange 56 and a slip collar 57 between which the gear 33 is frictionally clamped by a spring 58.

Both the flange 56 and slip collar 57 are cooperatively connected for rotation by a pin 59.

At its forward end the sleeve 55 carries the secondary dial 60 which, as has above beenstated, has its periphery divided into fourteen principal sections, each section again being subdivided into ten parts, and each of these parts representing one full revolution of the index pointer 41. The sleeve is also provided with a cam-plate 61 Fig. 7 provided with a notch 62 to receive, or permit the descent of, a pin 63 mounted for vertical movement in the casing and serving as a means for gaging the starting position of the secondary dial for any predeterminer'l number of yards to be measured, and also so that when the required number of yards has been measured, the thread will be cut off, and further rotation of the drum may then be prevented by a brake-mechanism to be hereinafter described.

As above stated, my present invention comprises a mechanism for cutting off the thread after a certain number of yards have been measured off, and in the present instance the action of the cutting mechanism iis controlled directly by the movement of Err twodevices, however, being such as to per mit'the device to be set for different lengths ,of thread to be measured before cutting off. Referring to Figs. and 8, it will be noticed that the sleeve carries near its front end a shell provided at its rear end with a cam disk 66, and havingat its front end a flange 67 provided with a radial extension 68 receive a screw 70 on which a detent 71 may (see Figs. 4 and 8), which is slotted at 69 to beheld. by a thumbnut72, the slot permitting the detent 71 to be moved toward the center of the sleeve 65, to engage any one of a series of notches cut on the periphery of the secondary dial in accordance with the sub divisions thereof.

The cam 66 is provided with a notch 73 (see Fig, 11) to permit the operation of the cutting mechanism, which in the present instance comprises a stationary plateor anvil v ,7 5 secured to a bracket 76 which is attached to the casing 25.

- Cooperative with the stationary plate or anvil 75, is a movable cutter blade 77 which is attached to a cutter spindle 78 by means of a screw 79, Figs. 2, 6 and 7 said spindle being journaled in the bracket 7 6 and having at its 7 forward endan arm 80 normally resting upon the top of a vertically movable actuator or pin 81, the lower end of which is adapted to Y ride 011 the disk 66 and is held in contact I ,therewith by a spring-actuated plunger 82,

' see Fig. 7.

' 8 In the present case, thedrawings illustrate the machine set to measure off 10,500 yards of material and to cut off the same from the supply on the instant when this quantity has 8 been measured off. Furthermore, the position'of the device as a whole is exactly on the starting line; or, in other Words, the device 1 is just ready to commence the operation of counting.

For this reason the cam 61, or more properly speaking, the notch 62 thereof, is disposed directly beneath the gage pin 63 and hence it will be seen that when the drum is rotated by the thread movement, said pin 63 will be gradually raised while at the same time the cam 66 will, by virtue of the detent 71 infengagement with the notch at 10,500 index mark on the second dial, be rotated under the pin 81 until the notch 73 of said cam will permit the same to drop, and coni sequently allow the spring plunger 82 to rock the "cutter carrying spindle 78 to bring the blade 77 into contact with the stationary plate-75,-.this action naturally occurring after the secondary dial has been rotated for a distance equal to 105 notches thereof, at which time the extension 68, Fig. 8 with the detent 71, will be perpendicularly disposed andin alinement'with the .zero mark on the stationary dial it belng understood, of course,

.1 7' that the cutter pin-81-is in vertical alinement withsaid mark-and, furthermore, that the notch 7 3 is in alinement with the center line of the extension 68.

In the operation of the device just above described, the movement of the index pointer ll can, as far as the operator is concerned,

be left entirely out of consideration, inasmuch as the device is used only for the purpose of cutting off the thread so soon as the required 10,500 yards of thread have passed over the drum. It will also be understood that by the mechanism above explained, and especially in view of the secondary dial 60 and its graduations, the operator is enabled to set the device so as to cut off the thread after any other desired number of yards of thread shall have been reeled off.

If the device is to be set, for instance, to cut the thread after 5,000 yards shall have passed over the drum, the operator would merely have to release the detent 71 from the secondary dial, then swing the extension 68 around (without, however, disturbing the secondary dial) until the detent 71 will come into alinement with the 5,000-mark on the secondary dial; by now moving said detent toward the center, the notch of the cut off cam will be brought into proper position to allow the pin 81 to drop after the 5,000 yards have been reeled.

It should be emphasized that the particular object or purpose of the gage pin 63 is to serve as an abutment for stopping the rearward setting movement of the secondary dial when the operator sets the device to the point of beginning operations, this construction permitting the operator to perform his duty by the sense of feeling rather than seeing, so that no possible mistake can occur, and the measuring device will be sure to start at the zero mark.

It is sometimes desirable to ascertain the capacity of different spools which vary in diameter as well as in length; and in order to provide a mechanism whereby the length of thread capable of being contained on a spool of any given size may be accurately determined, 1 deem it advantageous to use the index pointer 11 which, as above stated, travels over the index marks on the stationary dial 42 and one complete revolution of Which records 100 yards of thread passing over the drum.

Now inasmuch as under these circumstances the cutting'mechanism is not to be used, While on the other hand the movement of the secondary dial may be utilized to indicate notch by notch each 100 yards of thread passing over the drum and as recorded by each complete revolution of the index pointer 41, the cutter-actuating cam may be left out of consideration, and, therefore, en-

81. with suflicient pressure against the surface of the cam 66 to prevent inadvertent rotation thereof.

The operator can, therefore, by the aid of yard length being indicated by one full revolution of the pointer 41 over the stationary dial; and again, the secondary dial will move for the distance of one notch of its periphery for each complete revolution of the pointer 11 In order to facilitate the reading of the movement of the secondary dial with some amount of accuracy, I have provided an index pointer designated in a general way by 100 and comprising a plate 101, (see Figs. 9 and 10) which has a projecting lip 102 adapted to be positioned adjacent the fron edge of the secondary dial and in close proximity to the graduations thereof, or may be readily withdrawn therefrom.

In order to permit the withdrawal of the lip 102 so as not to interfere with the revolution of the detent 71 when the device is used for cutting off the thread, the plate 101 is slotted at 103 to receive a thumb screw 10% whereby the plate may be removably secured in position on the casing.

In Figs. 1 to 7 the linger plate 101 is shown in its retracted position; while in Figs. 9 and 10, said plate is shown cooperative with the front face of the secondary dial 60.

Means are provided for arresting the movements of the thread drum by a lessening of the tension of the thread as it is drawn therefrom, this decrease of tension being due either to slack or to the complete severance of the thread, whether intentional or accidental.

In the present instance the thread T passes through an eye or loop 105 which constitutes a part of a light-weight arm 100 rigidly secured on a brake shoe 107 which is pivoted at 108 to the casing and adapted to engage with the inner face 109 of the drum flange 22, above mentioned, it being evident that when the arm 106 falls, the surface 107 of the brake shoe 107 will be carried into contact with the flange in a manner clearly illus trated in Fig. 3, so that a wedging action of considerable force will take place immediately and therefore bring the drum to an instantaneous stop and thus arrest the movementof the entire mechanism.

Inasmuch as the mechanisms of my im proved measuring and indicating device comprise a number of elements which, in themselves, should be kept free from dirt and at the same time remain practically under constant lubrication, the casing 25 is preferably formed in the shape of a well adapted to rel l l 1 ceive a quantity of oil 0, Figs. 5, 6 and 7, which may be mtroduced into the easlng through an aperture 110 and a side pocket 111 of the casing 25.

The oil is taken up from the well by the e worm gear 28, and also by the worm 29, and gradually transmitted to the other movable elements of the mechanism, and inasmuch as it is essential to prevent the oil from escaping from the casing and being thrown around by centrifugal force, I provide the hub of the drum with the check ring or flan e 115, see Fig. 6, so that the oil cre ping through the bearings 2 1 will be thrown off at that point and into a groove 110 provided in the casing, for conducting such oil back into the well.

The device as a whole may be supported and positioned relatively to the spool in any convenient manner, and T have shown in the drawings the case 25 provided with an ear 120 for receiving a post 121, which may be carried by the spooling frame and to which the casing may be clamped by a set screw 121, as will be readily understood.

By referring to Fig. 6, it will be seen that the drum shaft 23 projects beyond the casing at both of its ends, so that in this wayl am enabled to operate and place the thread-drum onto either end of said shaft, thus making the device either right or left hand, as required, and without necessitating any changes what-- soever in the interior of the casing.

Inasmuch as the cutting off device, or more particularly the blade 77 thereof, should be substantially in alinement with the thread measuring portion of the drum, it would under those conditions be necessary to reverse the position of the cutter-supporting bracket, or to supply a new one on the other side of the casing.

The operation of my improved device is as follows :It being desired that the device shall cut off the thread after 10,500 yards have been reeled off, the operator will bring the detent 71 into alinement with the notch corresponding to the 10,500 mark on the secondary dial; this dial can now be turned around by hand in the direction of arrow a, see 4, until the pin 63 has dropped, and the dial may then be turned backward until it is stopped by said pin, in which position the 14,000 or 0 mark of the secondary dial is in exact alinement with the 0-mark of the stationary dial, or in other words: at the starting point.

It will be noticed that the distance to be traversed during the movement of the secondary dial when the latter is operated by the thread drum, will continue until the notch of the cam carried and controlled by the detent 71, will be directly under the cutter pin 81; or, in other words 105 notches will pass before said pin will be permitted to drop and thus allow the cutter spindle to cut oil the thread, at which time 10,500 yards will have been measured off, and the same operation 1 ma'yfnow be repeated ad tafim'tam.

In detail, the operation of counting and .ence of which is, as before stated, equal to one-fourth of a yard, Through the inter- Yvention of the worm 27 and worm gear 35,

the vertical spindle 36 is rotated at a slow rate of speed which is still further reduced by the worm and gear drive 39, 40 to drive the index pointer 41, which latter will make -one complete revolution for each four hundred rotations of the drum 20, so that this I complete revolution ofthe pointer indicates the passage of 100 yards of thread, on the stationary dial 42 which is graduated into 100 divisions so that, therefore, each yard of 20 thread as it is reeled off, can be readily determined. The rotation of the drum spindle 23'res'ult's also in driving the secondary dial .60 at a'very much reducedratio, by virtue of the worm and gear 27, 28, then the worm and gear 29, 30, and then the worm and gear 32, 33, which latter is in frictional connection I i with the dial and drives the latter at the "ratio of one complete rotation for each com- Jplete 56000 quartenyard rotations of the drum '20, so that, consequently, each com- I plete rotation of thesecondary, dial indicates the passage of 14,000 yards of thread over the drum 20. The periphery of the secondary dial is, as above stated, divided into 140 equal division-notches, so that each notch represents in reality the travel of 100 yards of thread; and inasmuch as a complete revolution of the, pointer 41 denotes a like amount, it follows that for, each complete revolution .of the pointer 41 the secondary dial progresses one notch in the direction of arrow'a Fig. 4. Now the cutter-cam is directly attached to the secondary dial so as to befrotated therewith (by virtue of the detent '71), and,i1 1asmuch as the drop-notch 73 of the cam is in alinement with the detent 71, it follows that, according to Fig. 4, the second ary dial can travel in the direction of arrow at forethe cam-notch 73 will come to a position under the plunger 81 whereby the cutter bladeis held-up in its inoperative position, and which will then immediately drop and cut the thread, at which time 10,500 yards of thread will have been reeled off.

On the other hand it will be understood that when the pointer 41 and secondary dial 5 60 are inthe position shown in Fig. 4, the machine may be set to cut the thread after any desired multiplefof 100 yards have been reeled over the drum, by simply bringing the detent71 into engagement with. the correspondingly indexed notch of the secondary I diah 1.
